the databases are not listed on either impala or hive. I checked if the user can see the /Hive/warehouse and an error popsout. Please see image.
WEBEX is available for faster resolution.
In general, your warehouse folder (/user/hive/warehouse) will have the following permission: 770 and the owner will be hive.
This will make sure only Hive user and group can only access, modify the data/db. it is required for your db security.
